文摘
- •
Sinassi Batholith is made up dominantly of TTG suite.
- •
Geochemical data show calc-alkaline metaluminous I-type signature.
- •
Average emplacement depths estimates is constrained at ca 16–18 km.
- •
Successive emplacement ages are ca 670–686, 661–666 and 644 Ma.
- •
Setting is consistent with a subduction-related magmatic arc of Andean-type.
